Hello Sharath,
Thanks for your reply.
I am afraid the issue in BUG JDK—8219086 is not the same as mine.
In the bug, the output of jhsdb jstack prints some mixed stack trace but does not \
print all the threads.
Within my issue, the output of jhsdb jstack can print all the threads but can only \
print the top of the stack trace.
And this issue can always be reproduced on latest Ubuntu (18.04),fedora (29) and RHEL \
8 Beta.
On the aforementioned OSs , The pstack can work well with java application. I am \
afraid there is something about compatibility between JDK and new Linux kernel or \
ptrace.
Best Regards

Hi Gao,
I also observed this failure and opened HYPERLINK \
"https://bugs.openjdk.java.net/browse/JDK-8219086"JDK-8219086 for it.
Thanks,

Subject: jstack mixed mode and jhsdb stack mixed mode can not get expected \
result(stack trace is incomplete) on latest ubuntu or fedora or RHEL 8 beta
Hello,
I tried "jstack -m PID"in latest openjdk 8 64-bit and "jhsdb jstack –mixed –pid \
PID" in latest openjdk 11 64-bit on latest Ubuntu(18.04) and latest fedora (29) and \
RHEL 8 Beta.
The stack traces returned are always incomplete like following output:
----------------- 1479 -----------------

0x00007f83922526d6 do_futex_wait.constprop.1 + 0x36
The issue existed even after I disable the selinux. It can not be reproduced on \
oracle linux 7.4.
The kernel version on Ubuntu or fedora is 4.15. the kernel version on RHEL 8 Beta is \
4.18. the kernel version on Oracle linux 7.4 is 3.1.
I can not find any existed bug for now.
Is there any clue about this issue?
Any reply will be appreciated.
Best Regards
Gao Shuai from GCS
